[Qt-interest] QMainWindow: Prevent mouse from leaving.

[Martin Guillon]

Doesn’t work for a qmainwindow. It wont prevent the mouse from leaving the window.Moreover it wont event send mouse move event when the mouse is out of the mainwindow.
And finally I want to hide the cursor. With grab the cursor can still leave the window and so wont be transparent.
